Your Free Virus Removal

Archive for the ‘Types Of Computer Viruses’ Category

This is craziness.  Just found this on the BBC!  It seems as if the government got some good use out of their computer security department.   I wonder if they use a free virus removal tool?  haha probably not… I’m sure they use some super secret virus protection they tell no one about.  I personally have never tried to hack the government so I wouldn’t know.  If I had tried I am sure I wouldn’t be writing to you right now.  It would be funny if I found out the government was using a free virus removal tool though.  Without further ado here is the article.

A widespread computer attack has hit several US government agencies while some South Korean government websites also appear to be affected.

The White House, Defense Department and New York stock exchange were all hit by the attack that started on July 4.

An analysis of the software used revealed its targets also included the National Security Agency, the Nasdaq stock market and the Washington Post.

Many of the organisations appear to have warded off the attack.

In South Korea, the presidential Blue House and Defence Ministry, National Assembly fell victim.

US officials have not released details of the attack.

Ben Rushlo, head of internet technologies at web performance firm Keynote Systems described it as a “massive outage”.

Amy Kudwa, a spokeswoman for the Department of Homeland Security said the body’s US Computer Emergency Readiness Team told federal departments about the issue and of steps “to mitigate against such attacks”.

Recently the US homeland security secretary Janet Napolitano told the BBC that protecting against virtual attacks was a matter of “great concern” and something the US was “moving forward on with great alacrity”.

The attacks in South Korea seemed to be connected to the attack of US government services, said Ahn Jeong-eun, a spokesperson at Korea’s Information Security Agency.

South Korea’s Yonhap News Agency is reporting that North Korea may be behind Tuesday’s cyber attack.

The country’s National Intelligence Service (NIS) suspects North Korea or its sympathisers may have been behind the attack, according to sources who spoke to the news agency on condition of anonymity.

It will present a report to the parliamentary intelligence committee on Thursday.

The attack slowed down and, in some cases, shut government websites, including the site of the presidential office, for several hours.

The government is totally using a free virus removal tool I know it!  Here is the real article:

I found this post while surfing the net to get the top viruses of last month! I managed to find a list as compiled by the folks that make Kaspersky. Seems like they are trying to keep on top of things!

There were 4 newcomers on the top 20 list as well as two viruses returning to the top 20.

The first Top Twenty is based on data collected by Kaspersky Lab’s version 2009 antivirus product. The ranking is made up of the malicious programs, adware and potentially unwanted programs most frequently detected on users’ computers.

Position Change in position Name
1 0 Net-Worm.Win32.Kido.ih
2 0 Virus.Win32.Sality.aa
3 6 Trojan-Dropper.Win32.Flystud.ko
4 Return Trojan.Win32.Chifrax.a
5 -2 Trojan.Win32.Autoit.ci
6 -2 Trojan-Downloader.Win32.VB.eql
7 0 Packed.Win32.Krap.b
8 -2 Worm.Win32.AutoRun.dui
9 New Exploit.HTML.CodeBaseExec
10 -2 Packed.Win32.Black.a
11 -1 Virus.Win32.Sality.z
12 New Virus.Win32.Virut.ce
13 New Trojan.JS.Agent.xy
14 -3 Worm.Win32.Mabezat.b
15 -3 Virus.Win32.Alman.b
16 -11 Packed.Win32.Krap.g
17 Return Packed.Win32.Klone.bj
18 -5 Worm.Win32.AutoIt.ar
19 New Exploit.JS.Agent.agc
20 -5 Email-Worm.Win32.Brontok.q

Making an impression this month were two newcomers, Virus.Win32.Virut.ce and Exploit.HTML.CodeBaseExec.

Virut.ce entered near the top of our second ranking in February and now looks set to dominate the first ranking as well. New versions of the virus are appearing every day, which suggests that cybercriminals are monitoring how and when the malware is detected by antivirus programs and trying to increase the size of the botnet made up of infected machines. The epidemic caused by this virus is gaining momentum and May could well see Virut.ce moving several places up the rankings.

The most interesting point in this article for me was the total number of different viruses found in the study by Kaspersky labs. The article states, “45190 unique malicious, advertising, and potentially unwanted programs were detected on users’ computers in April.” That sounds like a lot right? Well it is. There are 45190 different unique malicious programs that our computer are threatened by… and that is just what Kaspersky knows of. Who really knows how many are there but just undiscovered. That’s not the part that I found interesting.

The article then goes to say “This figure is almost exactly the same as last month’s.” That is the amazing part that got me! The number of viruses and malware have been growing by leaps and bounds over the past months to many times higher than last year. However, we kept it knocked down in april! Now either this means hackers have given up << not happening, or they are content with the viruses they have now and they are working enough that they don’t have to make new ones << more likely. Which means, LOCK UP YOUR COMPUTER!!!!! Check out the security guide posts and make sure you are locked up!

In this category, I will be sharing all the different types of computer viruses and what they do.

Wikipedia descibes a computer virus as:

a program that can copy itself and infect a computer without the permission of the owner. The term “virus” is also commonly used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability.  However, these are not actually viruses.   A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer. For instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

I will be covering many popular viruses such as: Facebook virus, conficker virus, XP Antivirus 2008, XP Antivirus 2009, latest computer viruses, downloadable viruses, new computer viruses, main types of computer viruses, names of computer viruses, computer and viruses, Limewire viruses.   These are all viruses you can use a free virus removal tool to get rid of so we are going to talk about them here!
